PATENT WINFIELD SCOTT RYNEARSON, OF BOISE, IDAI-IO.

DERRICK AND DUMPING DEVICE.

SPECIFICATION forming part of Letters Patent No., 665,757, dated January8, 1901.

Application'led June 19, 1900.

To @ZZ whom it' may concern:

Be it known that I, WINFIELD SCOTT RY- NEARSON, a citizen of the UnitedStates, and a resident of Boise city, in the county of Ada and State ofIdaho, have invented a new and Improved Derrick and Dumping Device, ofwhich the following is a full, clear, and exact description.

The invention relates to that class of machines which are provided witha mast mounted to turn in a suitable base and a boom carried by themast, together with a scoop which is supported from the boom and isarranged for dumping or for carrying a load.

The purpose of this invention is to simplify the construction ofmachines of this character and enable them to be readily placed inposition wherever desired; and a further and main purpose of theinvention is to provide a locking device capable of holding the scoop inposition to carry a load and enable the scoop to, be manipulated toreceivev a load and also to provide means 'for so operating thefastening device that the scoop may be quickly brought to a dumping ordischarging position.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter' fully set forth, andpointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective View of the improved device. Fig. 2 is ahorizontal section through the lower portion of the mast, showing thebase structure in plan view. Fig. 3 is a vertical section on the line 33 in Fig. 2 through the base structure of the device, illustrating themast in dotted lines as carried to a horizontal position. Fig. 4 is aside elevation of the scoop and a section through the locking device forsaid scoop, showing the scoop in position to carry a load; and Fig. 5 isa view similar to Fig. 4, illustrating the scoop in its dumping ordischarging position.

The base B of the device is usually attached to beams A, adapted to restupon the ground or upon the bed of a wagon, and the'base B, which is inthe nature of a frame, is connected senti No. 20,852. on mode.)

with the beams A through the medium of hinges 10, so that the base andparts carried thereby may be carried in direction of the ground forrigging purposes or for repairs or for other purposes. The base B may beheld in its horizontal position on the beams A by any suitable` means.For example, a hasp 1l may extend from the superstructurenamely, thebeams A, connected by suitable cross-bars-through a member of the baseB, and a pin 12 is then passed through the staple, to which pin a rope,cord, or chain 13 is attached.

A pulley 14 is located at each corner of the lower .structure upon whichthe base B is mounted, as shownin Fig. 2, and a hoist-rope,A

to be hereinafter referred to, is passed over any one of the pulleys 14,as occasion or convenience may demand. Braces 15 extend upward from thebase B and are connected at their upper ends to a ring or collar 16. Amast C is passed loosely through this ring or collar 16, and the lowerend of the mast is mounted to turn in the bottom structure formed by thecross-bars and beams A, while the Lipper end of the mast is mounted toturn in a cap 17, to which cap guy-ropes 18 are secured, and these ropesare led to the ground when the mast C is in an upright position and aresecured by pins 19 or equivalent devices.

rlhe mast is preferably tubular and is made in two or more telescopicsections`20 and 2l, the upper section being adjustably heldin connectionwith the lower section by a collar 22 and a set-screw 23, while a secondsetscrew 24, located in the lower section 20, is also utilized to engagewith the upper` section, thus preventing undue strain being brought tobear upon the upper set-screw 23. A pulley 25 is held by a clip orsuitable means to the upper section 2l of the mast at a point betweenits ends, as shown in Fig. 1, and at a point between the ends of thelower section 2O of the mast a second clip 26 is secured in any suitableor approved manner. One end of a boom 27 is hinged to the clip 26, theouter end of which boom 27 is usually provided with a head-plate 28a,extending above and below the boom. An adjusting-rope 28 is attached tothe upper end of the head-plate 28a, and the adjusting-rope is passedover the pulley 25 and down to the IOO lower portion of the mast, whereit is attached to a cleat 29 of any description. This adjusting-rope 28is adapted to regulate the inclination of the boom 27, and preferably asliding noose 30 is provided in this adjustingrope 28, through whichnoose the mast C is passed, so that there will be no undue strain on thecleat 29.

A block 3l is attached to the lower end of the head-plate 28a, securedto the outer end of the boom 27, and near the inner end of the said boom27 a second block 32 ,is placed. A hoist-rope 33 is passed over thepulleys in the blocks 3l and 32 and is carried downward over one of thebase-pulleys 14 and `from thence to any source of power'. Thehoistrope33 is att-ached to a lockingv device D for a scoop E, this lockingdevice and scoop being best shown in Figs. 4 and 5. i The hoist-rope 33is attached 'to the-upper end of a bar 34, which constitutes one memberof the locking device D. This bar is provided with a notch 35 in one ofits longitudinal edges and is provided near its upper end with a flange36, while one end of a chain 37 is attached to the lower end of the bar34 and to a hook 38 or the equivalent thereof, centrally located at theback or closed end of the scoop E. A casing 39 is provided for the bar34 ot' the locking device, and this bar slides in said casing and isadapted to entirely leave it when the scoop is to be brought4 to thedumping position. (Shown inv Fig. 5.) The upper flange, 36-'on'the bar34 limits the upward movement'of thefrcasing 39, and a plate 40, carriedbythe chain 37 and located adjacent to the hook on the scoop E, limitsthe upward movement of the rear end of the scoop, as shown in Fig. 5.trolled latch 4l has playin the casing 39, and when the bar 34 is in thecasing 39 the latch enters the notch 35 in the bar 34, as shown in Fig.4, and the latch 41 is held iu this locking position through the mediumof a lever 42, to which it is attached, the lever being pivoted tothecasing, which lever 42 extends downward to an engagement with the Lipperend of a spring-controlled keeper-bar 43, mounted to slide vertically orparallel withthe casing 39 in lugs 44, which are at one side of thecasing. The keeper-bar 43 is released from engagement with the latch 42by drawing upon a rope or cord 45, attachedtoysaid keeper-bar, at whichtime the spring of the latch `41 will force the lever 42 outward andwill carry the latch from engagement with the notch .35 in the bar 34,and the casing 39 of the locking device will` be free to drop downward.

The scoop E is provided at its receiving end with a suitable bail46,which is placed inconnection with a'snap 47 or like device attached tothe upperportion of the forward surface of the casing 39 ofthe lockingdevice.

In operation when the bar 34 islocked in the casing 39, as shown in Fig.4, the scoop E will normally so hang that its rea-r or closed Aspring-conend will be lower than its forward or receiving end, and therear end of the scoop may be manually raised or lowered, so as to gatherup material, and handles are usually attached to the sides of the scoop'to facilitate the gathering operation thereof. When the scoop hasreceived its load, it is permitted to return to the position showninFig. 4, and by pulling upon the hoist-rope 33 the boom is turnedaround the mast to any desired point, and said scoopis elevated at thesame time. When the scoop reaches the point where the load is to bedumped, it is simply necessary to pull upon the cord or rope 45,connected with the 4keeper-bar 43, and byfthus releasing the cas-" ing39 of the locking device from the bar 34 the casing will drop downwardalong the chain 37 until itstrikes' the plate 40, as shown in Fig. 5,thus `iu'ipari'iing to the` scoop E the forward andfdownwardpositionjshowni in Fig.

f5, which will compel thecon'tents of the scoop to slideY therefrom. Y

Havingy thus described my invention, I'
